I needed a tripod and two filters to get this shot. The tripod kept my camera steady for a long exposure. I used a graduated neutral density filter to reduce the brightness of the sky so that I could capture the entire scene with a single exposure despite the broad dynamic range. I added a neutral density filter to reduce the brightness of the entire scene even further – so that I could use a really long shutter speed. 25 seconds (at f/8) gave me a perfectly smooth surface of the lake – despite the choppy waters that morning. That long exposure let me simplify the image and capture the swirling colors on the surface of the lake.
